Repair options we may recommend

Drainage and minor repairs

Blocked weep holes are cleared or new ones drilled, and where practical a drainage layer is formed behind the wall with an outlet at its base. Loose copings are rebedded, open joints repointed and a few damaged bricks replaced. For a low wall that has not moved much, this can be enough.

Best for: Low walls that are damp or slightly weathered but still upright

Rebuilding on new footings

Where the whole wall is failing, it is replaced with a new retaining wall on a properly sized footing, with free-draining backfill, a membrane, weep holes and a drain at the base. Reinforced blockwork faced in brick or stone is common, so the wall matches its surroundings.

Best for: Walls failing along their length, or retaining significant height

What to expect when we carry out retaining wall repairs

Site assessment
On site we measure height and lean, check the drainage and the ground at the top and bottom, and look at access for digging out. Walls that support a drive, path or building, or retain more than a modest height, are referred to an engineer.
Written quote
You receive a no-obligation written quote covering demolition, excavation, temporary support, the footing, the new or repaired wall, drainage and spoil removal. It becomes a fixed price in writing once the repair is specified.
Build and drain
The failing section is taken down, the soil supported in short lengths, and the footing cast. The wall is rebuilt with drainage behind it, backfilled with free-draining material, and building control inspects where the work needs it.

Rules for retaining wall repairs in England

In England, underpinning and other work that alters or strengthens a wall or foundation is building work under the Building Regulations (Part A, structure), so building control approves and inspects it. Like-for-like repairs often are not, and we tell you which applies before a price is agreed. Work to a party wall, or excavation close to a neighbour’s foundations, can also need a notice under the Party Wall etc. Act 1996.

Your retaining wall repairs questions

What is the price of retaining wall repairs in Calne?

Guide prices for retaining wall repairs in Calne start from about £515 per wall, including VAT, on South West rates. Your fixed written price follows photos or a survey and depends on the extent of the work and access.

Do you carry out retaining wall repairs in Calne?

We do. Calne and the surrounding area are covered, including nearby Chippenham and Devizes. A free initial assessment from your photos is the first step.

Does the ground around Calne cause cracking?

Southern Wiltshire is chalk, while the north around Swindon, Chippenham and Trowbridge sits on Oxford and Kimmeridge Clays that are prone to seasonal movement near trees. Bath stone was mined underground around Corsham. Only an investigation can say why a particular building has moved.

Is a leaning retaining wall dangerous?

It can be, especially if the lean is getting worse, the wall is tall, or there is a path, drive or building next to it. A wall that has leaned slightly for decades may be stable, but one that has moved recently should be kept clear and assessed soon.

Do I need an engineer for a retaining wall?

For low walls holding back a planting bed, often not. Walls retaining more than a modest height, often taken as more than about a metre, or supporting a drive, path, building or neighbour’s land, generally need an engineer’s design. An independent chartered structural engineer is appointed where needed, and we can arrange this.
